运行具有特定开始,结束日期和时间限制的Quartz Scheduler作业 [英] Run Quartz Scheduler Job with specific start, end date and within time constraints
问题描述
我使用Quartz-Scheduler重复任务,但我面临麻烦。在我的服务器端,我的用户希望指定一些日期范围,例如从 2013-09-27
c $ c> 09:00 AM - 12:00 PM 到 2013-09-30
I am using Quartz-Scheduler for repetitive tasks but I am facing a trouble. In my server side my user wants to specify some date range like From 2013-09-27
with in 09:00 AM - 12:00 PM
to 2013-09-30
说明:
Explanation:
从 2013-09-27 到
2013-09-30
但仅在 09:00 AM - 12: 00 PM
我在编写Cron表达式时遇到麻烦,此外,我的用户是非技术性的,因此我的用户希望我创建从两个时间戳值自动生成Cron表达式。
I am facing trouble in writing a Cron expression for it, furthermore my user is non-technical so my user wants me to create Cron expression automatically from both time stamp values.
请帮助我。让我知道是否有另一种方式。
Please help me out. Let me know if there is another way.
我在Google上看到了很多资源,但我还是找不到任何东西。
I have seen many resources on Google but I still can't find nothing.

在UNIX / linux中的cron表达式允许指定确切的开始和结束日期
更新
我写了一个,但不起作用
I have written one but it's not working
|------------------------------------------------------------------|
| Seconds | Minutes | Hours | DayOfMonth | Month | DayOfWeek | Year|
| | | | | | | |
| 0 | 0 | 9-12 | 27-30 | 9 | ? | 2013|
|------------------------------------------------------------------|
试图映射 2013-09-27
到 2013-09-30
,但只在 09:00 AM - 12:00 PM
更新
我也尝试过使用
Updated I have also tried it running with
Trigger trigger = TriggerBuilder.newTrigger().withIdentity(NAME_TRIGGER_TASK_UPDATER, GROUP_TASK_TRIGGER)
.withSchedule(CronScheduleBuilder.cronSchedule("0 0 9-12 19-22 10 ? *")).build();
但它不会给出任何错误或进入我的作业的执行方法
but it doesn't give any error nor go into my execute method of my job
cronSchedule("0 0 9-12 ? * ?") throws invalid schedule exception.
下面的代码运行它而不考虑开始和结束日期。
The code below runs it without respecting the start and end date.
String startDateStr = "2013-09-27 00:00:00.0";
String endDateStr = "2013-09-31 00:00:00.0";
Date startDate = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.S").parse(startDateStr);
Date endDate = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.S").parse(endDateStr);
CronTrigger cronTrigger = newTrigger()
.withIdentity("trigger1", "testJob")
.startAt(startDate)
.withSchedule(CronScheduleBuilder.cronSchedule("0 0 9-12 * * ?"))
.endAt(endDate)
.build();
推荐答案
不工作?
您可以尝试以下代码(编辑:适用于Quartz 2.2)。此方法不在cron表达式中指定开始/结束日期和年份,而是使用Trigger方法来指定它们。
(注意:我自己没有测试,请告诉我是否适合你)
You can try the following code ( applies to Quartz 2.2). This approach does not specify the start/end dates and year in the cron expression, instead uses the Trigger methods to specify them. (Note: I haven't tested it myself, let me know if it works for you)
编辑:
我有机会测试这段代码,我运行下面的代码,并不断更改系统时钟,所有的触发器从上午9点到上午12点,从开始到结束日期成功。
I had the chance to test this code, I ran the code below and kept changing the system clock and all triggers were successful between 9 am to 12 am from start to end date.
public class CronJob {
public static void main(String[] args) throws ParseException, SchedulerException {
Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
JobDetail job = newJob(TestJob.class)
.withIdentity("cronJob", "testJob")
.build();
String startDateStr = "2013-09-27 00:00:00.0";
String endDateStr = "2013-09-31 00:00:00.0";
Date startDate = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.S").parse(startDateStr);
Date endDate = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.S").parse(endDateStr);
CronTrigger cronTrigger = newTrigger()
.withIdentity("trigger1", "testJob")
.startAt(startDate)
.withSchedule(CronScheduleBuilder.cronSchedule("0 0 9-12 * * ?").withMisfireHandlingInstructionDoNothing())
.endAt(endDate)
.build();
scheduler.scheduleJob(job, cronTrigger);
scheduler.start();
}
public static class TestJob implements Job {
@Override
public void execute(JobExecutionContext context) throws JobExecutionException {
System.out.println("this is a cron scheduled test job");
}
}
}
工作,尝试用cronSchedule(0 0 9-12?*?)替换cronSchedule(0 0 9-12 * *?)
If the above code does not work, try to replace the cronSchedule("0 0 9-12 * * ?") with cronSchedule("0 0 9-12 ? * ?")
